The ex-Goldman Sachs partner set up boutique advisory firm Simon Robertson Associates in 2005. Last year Robertson teamed up with former Morgan Stanley banker Simon Robey, changing the firm's name to Robertson Robey. During his time at Goldman, Robertson worked on major deals involving the likes of BAE and GlaxoSmithKline. Robertson Robey yesterday emerged as an adviser to Vodafone's board on the company's £6 billion takeover of Spanish cable company Ono.
